And a little magic to help him look his best? He's already had a bath. He was someone's cat before or he just likes water. [He assumes that's possible. Church never had but Church hated everything except his favorite treats and tricking people into rubbing his tummy so he could claw them.] There were some mats I couldn't get out without cutting them off so I left them. I didn't want to break his trust by scaring him.

Shadowhunters can see through most glamours. [Not Magnus' better ones but he doubts that Magnus would use that much power just to glamour Alec's favorite tea.] Unless you're going to use the type you use on your eyes.

Oh. I wouldn't be surprised if you could cast a spell like that from a distance.
